Industrial Applications of (PHENYLTHIO)ACETIC ACID
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Key intermediate in the synthesis of penicillin-class antibiotics (e.g., penicillin V, ampicillin) | Acylated with 6-APA (6-aminopenicillanic acid) to construct the side-chain structure |
| Pesticides | Synthesized into certain sulfur-containing organic pesticides and plant growth regulators | Participates in condensation or substitution reactions to introduce the phenylthioacetyl functional group |
| Organic Synthesis | Used as a precursor for sulfur-containing heterocyclic compounds or chiral ligands | Reacts with alkyl halides or carbonyl compounds under basic conditions to form C–S or C–C bonds |
| Analytical Chemistry | Chelating agent for metal ions (e.g., copper, mercury) | Forms stable complexes with metals via its thiol and carboxyl groups, applied in colorimetric or extraction analysis |
Manufacturing Quality Control of (PHENYLTHIO)ACETIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies active compound by neutralizing carboxylic acid group with standardized NaOH solution using phenolphthalein indicator. |
| Water Content | Karl Fischer Titration | Measures trace water via iodine-sulfur dioxide reaction in methanol-based reagent, with electrochemical or volumetric endpoint detection. |
| Color | Visual Comparison or Spectrophotometry (APHA/Pt-Co Scale) | Evaluates yellowish discoloration by comparing sample color to platinum-cobalt standard solutions or measuring absorbance at 430 nm. |
| Acidity (as H2SO4) | Acid-Base Titration | Determines total acidic impurities by titration with NaOH using methyl orange indicator. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing. |
| Heavy Metals (as Pb) | Lead Sulfide Colorimetry (USP/EP) | Forms black PbS precipitate in presence of H2S under controlled pH; intensity compared visually or spectrophotometrically. |
| Chloride | Silver Nitrate Titration | Quantifies chloride ions by precipitation with AgNO3, using potassium chromate indicator for endpoint detection. |
| Sulfur Compounds (e.g., benzyl mercaptan) | Gas Chromatography (GC-FID) | Separates and quantifies volatile sulfur impurities using flame ionization detection with appropriate column and calibration. |
| Density | Digital Density Meter | Measures mass per unit volume at specified temperature using oscillating U-tube principle. |
| Refractive Index | Refractometry | Determines ratio of light velocity in air vs. sample using critical angle measurement at 20 C. |
| Melting Point | Capillary Melting Point Apparatus | Identifies temperature range at which solid transitions to liquid, indicating purity and identity. |
| Organic Volatile Impurities (e.g., benzene, toluene) | Gas Chromatography (GC-MS) | Separates and identifies residual solvents by retention time and mass spectral matching against reference standards. |
